Author: Jakub Palaczynski

CVE (Administrator): CVE-2017-14524  
CVE (Webtop): CVE-2017-14525  
Affected software:  
Documentum Administrator  
Documentum Webtop  
Exploit was tested on:  
Documentum Administrator version 7.2.0180.0055  
Documentum Webtop version 6.8.0160.0073  
Other versions may also be vulnerable.  
Open Redirection - 2 instances:  
Please note that examples below are for Documentum Administrator, but  
the same exploitation takes place in Webtop.  
1. First instance:  
It is possible to frame custom/malicious website on a trusted domain.  
This way an attacker may for example steal credentials via creating  
fake login form or redirect users to a malicious website.  
Proof of Concept:  
2. Second instance:  
It is possible to redirect user to custom website. Besides redirection  
it also allows for stealing sensitive data - before redirection takes  
place application appends username and base64 encoded user's encrypted  
password ("ticket" parameter).  
Proof of Concept:  
Please note that PoC below works only in Internet Explorer browser as  
only this browser treats /%09/ as //, which makes redirection work.
